Efficient syntheses are described for the new bridging bis-phosphanes DPPN (4) and DPEN (5) built around the restricted rigidity of a 2,7-dialkoxynaphthalene backbone. These show marked preference for bridging pairs of metal atoms (PtII, Mo0) to form metallamacrocycles or oligomers. Single-crystal X-ray structure determinations of four dimeric complexes with PtII and Mo0 are reported. The dimeric platinum
描述了围绕 2,7-二烷氧基萘骨架的受限刚性构建的新桥接双膦 DPPN (4) 和 DPEN (5) 的高效合成。这些显示出对桥接金属原子对(PtII,MoO)以形成金属大环或低聚物的明显偏好。报告了四种具有 PtII 和 MoO 的二聚体配合物的单晶 X 射线结构测定。二聚铂配合物可以作为动力学有利的反式,反式产物获得,其在游离配体存在下异构化为顺式,顺式形式。cis,cis-[Pt2Cl4(DPEN)2] (12) 显示出显着的加氢甲酰化催化活性。
